, The present invention relates to gauge devices of the character known in the oil fields as an'oil thief, the purpose of WlllCll'lS to determine the amount of sediu'lent or settlings contained in a crude oil tank, the particular settlings in question being the basic sediments known in the oil fields as B. S.

Objects of the invention are to provide ajf a being held to the faces of the member by gauge which will be simple in its operation 10 and which may give accurate results in the hands of inexperienced persons and which will not fill except as an accurate gauge ofI the contents of a tank. 7

Another object is to provide a'gauge which will be accurate to a small degree, as a quarf ter, inch, in gauging the depth of sediment in a tank;

A still further object is to provide a construction whereby the cups for catching the 00 1 7 Ina e )rotected 'i ainst breaka e r r hqmd y b t a ends of each cup being on. a horizontal 11116 when the device is not in use.

Referring to the drawings in detail by reference numerals, it Wlll be noted that the gauge comprises an elongated hollow member 10,'triangular in cross section asshown injFigure 3and having on two of its outer faces plurality ofcups 11, said cups means of brackets 12thaving a Vertical port1on13,from the lower end of which extends with .curved, laterally arranged arms 15 adapted to embrace the cylindrical walls 16 of the cups.

The other "face may lrave'siinilar rows of cups, the cups in each row being'in staggered relationship tothe cups in the other row, and the cups on this face may besoarranged as to be positioned to catch sediment at levels half way between the cups onthe other face, that is, considering thecupson the one face as catching sediment on the inch and half inch, the cups'on v filling them with foreign substance.

ment is that When gauging theidepth ofsedithe other face willcatch sediment on the quarter and three-quarter levels. Theface on which the cups catchjsediment on the inch and half inch may be designated by the nu- V meral 10a, and the face on which the cups catch the sediment on the quarter and threequarter inch levels may be designated by the numeral 10?). z The purpose, of making the gauge in the form of a triangular member is to provide a fiat surface on the facelOo which may be laid fiat onthe ground when the thief isnot in use,

In'other words, ifthe cups up to 1 the five inch levelshould contain sediment,

it will be apparent that the depth of such sediment is three feet five. inches as comd pared with threefeet at the previous reading.
